The A to Z of biometrics

Accuracy

Some biometrics are more accurate than others. Iris is generally considered to be the most accurate, followed by fingerprint then face.

Accuracy is usually determined by measuring the False Acceptance Rate - i.e. allowing in imposters - and the False Rejection Rate, which is when an authorised user is barred.

Accuracy will depend on the particular technology or mix of technologies involved and also the conditions under which they are being measured. For example, it's easier to capture a voice pattern in a quiet room than on a noisy street.
